Ask your customers to imagine that they're selling your product at a trade show, retail outlet, or public market. Give them a few cardboard boxes and ask them to design the product box that they would buy. The box can contain anything they wantmarketing slogans that they find interesting, pictures, price points. They can build elaborate boxes through the materials you'll provide or just write down the phrases and slogans they find most interesting. When finished, ask your customer to use their box to sell your product to you and the other customers in the room.
